When Minato initially entered KCM, he needed Yang Kurama's cooperation to enter that state, meaning all this time he was accessing Kyūbi's Yang Chakra and not the Yin Chakra inside him
could it be a limitation imposed by the Shiki Fūjin? That's he's not truly capable of utilizing the Yin Chakra sealed inside him?
It implies that even when sealing Yin Kurama inside him, he's not truly a Jinchuuriki, who is able to access the power of the Bijuus sealed inside him, hence the words "Non-Jinchuuriki"
Here is a scan which possibly adds credence that Minato is using Kurama's Yang and not Yin:
"Can you toss a bit more Chakra my way?!" It seems to imply that Yang Kurama's Chakra is supplementing both Naruto and Minato's kcm two-ways
And Naruto having the need to turn off his KCM to enter BM later implies that a large portion of the Yang Chakra is being used by Minato atm
So ultimately, it means that Minato could just possibly be using Kurama's Yang Chakra akin to Chakra Transfer to enter KCM? And that the Yin half isn't or can't be used by Minato for not being a true Jinchūriki
Finally:
Doesn't appear to me that Yin Kurama is channeling his Chakra to Minato, his hands aren't clasping like Yang Kurama does (to transfer chakra) not to mention Minato is surprised of him suddenly talking. I think we shall soon find out that Minato isn't truly a true Jinchūriki but merely a container of Yin Kurama without the capability to tap that Yin power
